KNOCKDOWN PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 436,142, datedSeptember 9, 1890. Application filed January 13, 1890. Serial No.336,771. (No model.)

To all whom, it may concern.-

Be it known that l, ALBERT C. LOHMANN, a cltizen of the United States,and a resident of Akron, county of Summit, and State of Ohio, haveinvented certain new and useful Improvements in Knockdown Boxes, ofwhich the following is a specification, the principle of the inventionbeing herein explained, and thc best Inode in which I have contemplatedapplying that principle so as to distinguish it from other inventions.

My invention relates to knockdown boxes. My especial object in thisinvention is a form of box containing the advantages of the form hereinshown, described, and claimednamely, a box that may be set up at anytime,

' as well after pasting as before, so that it may be shipped in itsknockdown form and will not require expert labor to set it up. Incornbination with the above feature I form the side panels of the boxand the paste-flap of equal width, whereby I am enabled to cut theblanks continuously on a machine Without waste of material, and makecomplete boxes identical in appearance, as hereinafter more fully setforth.

' In my present form I arrange the .scoring on the inner tuck-hap sothat it may be cheaply scored on a machine, the angle of the score beingsuch that the same machine may be used to secure any-sized box byan easyadjustment, whereas in other cases the angle of said score was such thatit was with great difficulty the adjustment could be made `gor scoringeach variation in the size of the It will be understood that in machinesfor scoring and making boxes the scoring knives or instruments are setup and secured to a cylinder, and it is far easier to secure saidscoring-knives so as to form scores at right angles to each other or atangles of forty-five degrees to each other than at any other angle. Onthe other hand, if the diagonal score of the inner tuck-lap in asmall-sized box is extended in a direction at variance from forty-fiveor ninety degrees, with every variation in the size of the panelcontaining said score a corresponding change in the angle 5o of saidscore relative to the other scores of the panel would beabsolutelynecessary, and time, labor, and expense would thus be wasted. To any oneskilled in theart of box-making by machinery this will be evident, andto such a one the importance and advantage of the form of box hereindescribed will be obvious.

Figure l is a plan View of a box-blank formed according to thisinvention. Fig. 2 is a plan view of the box in knockdown form ready forshipping. Fig. 3 is a front elevation view of the box with the innertuck-flap folded into position; and Fig. 4 is a plan view of twocompanion blanks illustrating how they interfit with each other.

A piece of straw-board or other box material is so scored as to definefront and rear panels, respectively, C and A, and side panels B and D,and the paste-flap E. The top corner tuck-flaps F are respectivelyintegral with the panels B D. The usual top or cover tuckiiap G is alsoprovided, and integral with this is tuck-flap g. The bottom portion ofthe boxblank is cut and scored so as to form bottom panel L integralwith rear panel A, said bottom panel being provided with bottom tuck-hapZ. The bottom corner tuck-flap his integral with panel D, and bottompanel H is integral with side panel B, but free from bottom panel L. Theinner side flap J is formed integral with bottom panel H and free fromfront panel C. Top tuck-panel b is integral with inner side tuck-flap J,the score b deining the separation of the two. The inner side tuckflap Jis provided with the diagonal score j, that extends at an angle offorty-five degrees from lower extremity of score h', which outlines theseparation between panels H and J. In other words, said score j extendsfrom thel lower corners of panels Hand J to a point where the upper freeedge of panel J meets the lower common corners of panels C and paste-napE. The tuck-Hap J greatly strengthens the box and also serves to holdtuck-Hap g in closed position, as said flap g is tucked in between ap Jand C, and the weight of the box contents pressing against flap J servesto bind ap gbetween J and C. The distance from score h to score b shouldbe equal to the length of panel C, in order that the inner tuck-Hap Jmay extend the entire length of panel C. The lap b may then be bent overas an 'aid to securing a tight cover. Under the construction above de-IOC scribed the distance of score j, Where itintersects panels C and E,from the common point of intersection of panels .I C B II is equal tothe width of panel C, and in this form of box said score j is alwaysformed at an angle of forty'iive degrees to score h and the cut thatseparates panels C and J. It Will further be noticed that the length ofbottom panel II and width of panel C are equal. Thus score 7L and theout separating panel C and flap J, together With score j, outline anisosceles triangle, of which the score-line j is the base.

It will be noticed thatpaste-llap Eis of the same Width as panels B andl), so that either of the outer panels E or D may be used as apaste-flap. This forming the outer flaps of equal Width enables me toreverse the blank and lit the heads of the same together, as shown inFig. l, and I can thus continuously score and cut said blanks on amachine without Waste of material. This is a point of great utility,particularly in boxes formed with an inner tuck-flap and such as Iherein show, as otherwise they could not be cut contin uously on amachine nor without great Waste of material. It will be further noticedthat the top tuck-flap g and the bottom flap Il are located in differentplanes at right angies to each other in the complete box and indifferent longitudinal planes in the blankthat is, II does not lie inthe same longitudinal plane bounded by scores bounding flap g and panelsG A L and flap l, While B and H lie in the blank in the samelongitudinal plane, but in the completed box are in planes at rightangles to each other and at right angles to the plane of the toptuck-flap g, said flap II and panel B being integral and separated onlyby a score-line at the bottom edge of the box.

rlhe foregoing description and accompanying drawings set forth in detailforms embodying my invention; but change may be made therein, providedthe principles of formation respectively recited in the following claimare employed. I therefore particularly point out and distinctly claim asmy invention- A knockdown paper box provided with front and rear panelsC and A, side panels B, D, and E, of equal Width, whereby either of theextreme side panels may be used interchangeably as a paste-flap, toptuck-flap g, and bottom liap II, located in diferent planes at rightangles to each other in the complete set-u p box, said iiap II and thecentral side panel B being located in the completed box in planes atright angles to each other and at right angles to the plane of thetuck-Hap g, and the flap II being integral With the panel B, innertuck-flap .I integral With the flap II and separated therefrom by ascore h', said Hap J free from but immediately adjacent to the frontpanel C and extending across the entire Width of said panel and providedwith the diagonal score j, extending at an angle of forty-ve degreesfrom the score 7L', whereby the said panel .I may be folded and insertedwithin the box to form a pocket for the top tuck-ilap g, substantiallyas set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this Sth day of January, A. D. 1890.
